Hi.

I am going to have to do some welding to the body work of the boot (trunk) of my car.

Clearly at some point water has got in, the carpet has got wet and its rotted out :(

The boot was carpeted and the paint work wasn't really visible however the original paint in there was just the factory paint same as the exterior. My intension is to replace the carpeting when I am done.

How would you paint the boot of a car like this (note it's never going to be "showroom" condition, not for some time at least). Is just 2 or 3 coats of epoxy primer going to be good enough or does it need something over the top of that?

Cheers

Ah, finally a question I know something about.
You don't actually mention rust but if the carpet rotted out then I assume there is?
If so you need to get back down to the metal, that can be done with an aggressive wire wheel on an angle grinder and you may have to actually grind as well depending on how deep the rust is into the metal.
In any case removing the old paint/ carpet glue or heavy rust you still need clean solid metal before you apply 2 coats of 2k epoxy primer.
The epoxy primer will probably hold up without a topcoat but there are many good quality topcoats designed just for trunks that will protect the epoxy for decades.

Depends on what a "car like this" actually is.

I used Zolatone on the trunk of this '65 Buick:

Sorry I neglected to add that when I said "rotted out", I did indeed mean "rusted out". Not sure if that is a Britishism.

Second "A car like this" is a Jaguar XJS, but its in pretty rough shape and I am trying to save it.

These are pictures of the above trunk before I removed all the rust and installed new pans.

The only thing to do with rust is remove it. If that means installing new trunk floor supports, pans and extensions, that's what you do.

Two choices Half **** it OR do it right.
I only have advice on one way to do it my self.
I my self enjoy heavy Structure rust repair work, I enjoy it more than Body filler work or painting. almost as much as Engine building or Transmission rebuilds!

This repair on my car is usually done by cutting the new floor pan up into small chunks and then welding it all in in pieces. to me this is half **** approach and it always shows! I myself wanted a repair that could not be detected unless you really go looking for it. This required installing the pan in one piece.

I started this Project years ago and its still not done! although it is getting closer to completion, But I only work on it in my spare time on my days off from my real job and in between other projects it takes a back seat to a lot of other stuff! Since I started it I had to get another lift, another Tig welder, and a Rotisserie and added other tools as well.
A Project like this can take years to complete don't get discouraged take your time do your research talk to others that has done the job find all your parts! and Most of all Practice! your techniques before working on your project!

Once you get enough of the Real cancer out Then you can concentrate on cleaning and reconditioning the Parent metal you intend to reuse.
